Working principle of slow wire processing

 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

Car glass cleaning is very important in rainy weather

The cleaning of car windows is not only an issue of appearance, but also a necessity in terms of safety. Especially on rainy nights, the dazzling oil film will affect the field of vision and must be removed immediately. If it is slightly dirty, you can wipe it with a towel and car without using a car body cleaner. You can wipe it off immediately or remove the oil film. After the dirt is completely removed, apply a protective agent, which can make the oil film difficult to adhere.

1. Dirty car windows threaten safety. When driving at night on rainy days, the wiper wiped off and the residual oil film is dazzling, which greatly affects the vision.

2. Thoroughly clean the windows of the car, the vision is immediately clear, and it is easier and safer to drive at night.

3. If the oil film attached to the glass is difficult to remove by ordinary methods, use a chemical synthetic agent for removing the oil film to wipe it.

4. Not only the outside, but also the interior of the glass must be wiped. The insulation line must be wiped horizontally. If it is wiped vertically, the insulation line may be broken.

5. A car window protectant that can effectively prevent dirt and oil film from adhering to the glass surface. But before use, you must clean the car windows, otherwise it will be difficult to have an effect.

6. After the protective agent dries, it will turn white just like waxing. Just wipe it off with a soft cloth.

7. After the protective agent is applied, the water will roll off in granular form. If the rain is not heavy, you don’t even need to activate the wiper.

8. There are also protective agents added to the water tank. Just clean the windshield before use, otherwise the effect will not be good.
